CARBURETOR.

SPECIFICATION forming part of Letters Patent No. 257,247, dated May 2, 1882.

` l Appucnimnnied Jammyerisaa. (No modem To all whom it may conce-ra:

Be it known that I, IRA W. SIIALER, a citizen of the United States of America, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Oarburetors; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to whichitappertains to make and use the same, reference bein g had to the accompanying drawings, and to letters or igures of reference marked thereon, which form a part of this specification, and in which- Figure 1 is a side elevation. Fig. 2 is a ver- Fig. 3 is a cross-section taken on the line y y of Fig. 1. Fig. 4 is a side elevation of one of the composite globes or balls into which the absorbent is formed. Fig. 5 is a side elevation ofthe cylinder G. Fig. 6 is a top View of the partition D, showing the pipe C in cross-section.

Myinvention relates to improvements in devices for enriching gas and carbureting air, and has for its object the providing of a simple, cheap, and efficient gas or air carburetor, which will be safe against explosion in case of lire or ignition by careless treatment or design; and it consists in the construction and arrangement of parts and of the composition and formation of the absorbent, as will be hereinafter more fully set forth.

A represents the reservoir or outer shell of the carburetor; B, the inlet-pipe for the air or gas, and O the outlet-pipe, that may communicate with other pipes or have a burneror service-pipe attached to it, as may be required.

In constructing this device the inlet and outlet pipes for the gas or air are placed in the top of the reservoir, and extend above it for the purpose of preventing gas or carbureted air from owing through them except when the outlet-pipe is opened and a current of air or gas established through the carburetor. This construction prevents absolutelyr the escape of oil into the distrilniting-pipes through the overchargi n g of the carburetor.

The reservoir is divided into two compartments or chambers `by a partition, D, made of wire matting or gauze. The upper compartment,E,includes all that part of the reservoir aboie the partition D, which is ordinarilyabout one-fourth of the reservoir, and constitutes an air-chamber. lllhe inlet-pipe B opens into the top of the chamber E, and the outlet-pipe C passes through the top, at or near the center, through the air-chamber E and partition D,

and down to a point near the bottom of the reservoir. The lower compartment, F, contains a hollow cylinder, G, made ot' wire Inatting or gauze, and is provided with a bottom of any suitable material, from which projects upward, from a point at or near the center, a tube, H, ot' perforated metal, for the passage of the outlet-pipe O to a point near the bottom of the reservoir. rI he tube H is of sufficient diameter to permit the easy passage of the pipe O, and the hollow cylinder G is of sufficient diameter to pass freely into the reservoir.

- The hollow cylinder (nl, between the tube H and the sides ofthe cylinder, is filled with the absorbent of the carburetor that holds. the light products ot' petroleum, giving the same off by evaporation to a current of air or gas as itvpasses th'rough it. The absorbent is composed of granulated peat, two-thirds, by measure, and plaster-of-paris or any other suitable porous material forunitiug the peat and forming it into globes or spheres I, one-third.

In preparing the globes Ithedrygranulated peat is mixed with ground plaster-of-paris,saturated with water, aud formed into globes by a machine especially constructed for thev purpose. During this process the plaster sets. The globes are then allowed to dry, becoming porous bodies, and, being true spheres, when the chamber F is filled with them but a small portion ot' their surface is covered by contact, the most of it being exposed tothe current ot' air or gas that passes from the air-chamber E down through partition D, and, searching its waybetween the globes, reaches thelowerend of the exit-pipe (l and passes out surcharged with hydrocarbon gathered from the globes.

In charging the carburetor any ot' the vola' tile oils may be used. Poured into the inletpipe B, it distributes itself over the partition D and finds its way down through the globes I from one to another by capillary attraction until all the globes are saturated. All surplus of oil, if any there be, settles to the bottom, where it is drawn oft' through a spigot, J, the
